Topological Unwinding in an Exciton-Polariton Condensate Array
Guitao Lyu, Yuki Minami, Na Young Kim +2
The phase distribution in a Bose-Einstein condensate can realize various topological states classified by distinct winding numbers. While states with different winding numbers are…
Exciton-Polariton Quantum Simulators
Na Young Kim, Yoshihisa Yamamoto
A quantum simulator is a purposeful quantum machine that can address complex quantum problems in a controllable setting and an efficient manner. This chapter introduces a solid-sta…
Exciton-polariton condensates in zero-, one-, and two-dimensional lattices
Na Young Kim, Yoshihisa Yamamoto, Shoko Utsunomiya +3
Microcavity exciton-polaritons are quantum quasi-particles arising from the strong light-matter coupling. They have exhibited rich quantum dynamics rooted from bosonic nature and i…
Spatial correlation of two-dimensional Bosonic multi-mode condensates
Wolfgang H. Nitsche, Na Young Kim, Georgios Roumpos +4
We studied the spatial coherence of a Bosonic two-dimensional multi-mode condensate both through measurements and simulations. It is shown that condensates with a constant spatial…
Exciton-polariton condensates
Tim Byrnes, Na Young Kim, Yoshihisa Yamamoto
Recently a new type of system exhibiting spontaneous coherence has emerged -- the exciton-polariton condensate. Exciton-polaritons (or polaritons for short) are bosonic quasipartic…
Algebraic order and the Berezinskii-Kosterlitz-Thouless transition in an exciton-polariton gas
Wolfgang H. Nitsche, Na Young Kim, Georgios Roumpos +5
We observe quasi-long range coherence in a two-dimensional condensate of exciton-polaritons. Our measurements are the first to confirm that the spatial correlation algebraically de…
